CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation-in-part of International patent application No. PCT/US2013/048159, entitled “Oral Examination,” filed Jun. 27, 2013, the entire disclosure of which is hereby incorporated herein by reference.

The present application also claims the benefit of and priority to U.S. Provisional Patent Application No. 61/825,712, entitled “Optical Filtering Attachment,” filed May 21, 2013, the entire disclosure of which is hereby incorporated herein by reference.

BACKGROUND OF THE DISCLOSURE

In oral cancer screening, diagnoses can be limited by lack of comprehensive and accurate image libraries to assist in assessing clinical images of abnormal tissue. Current methods of imaging such tissue involve the use of Digital Single Lens Reflex cameras (DSLRs), which may be challenging to use for those without extensive photography skills, have inadequate depth of field for imaging abnormal tissue, and may be limited in use to specific or qualified personnel. Existing image libraries are online only and do not provide the care giver with information to assist in making a clinical decision.

DETAILED DESCRIPTION

It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of various embodiments. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. Additionally, the term “lens” as used herein may mean an optical component that diverges or converges an optical beam as well an optical component that does not converge or diverge an optical beam.

FIGS. 1-3 are perspective, front, and exploded views, respectively, of at least a portion of apparatus 100 according to one or more aspects of the present disclosure. Referring to FIGS. 1-3 collectively, the apparatus 100 may comprise a housing 105, a first end cap 110, an interstitial member 115, and a second end cap 120, all coupled end-to-end in the order listed, as shown in FIG. 1. However, the housing 105, the first end cap 110, the interstitial member 115, and the second end cap 120, a subset thereof, and/or additional components may be coupled or otherwise interconnected in a manner other than as shown in FIG. 1, and such implementations are also within the scope of the present disclosure.

The housing 105 may be or comprise a partially or substantially cylindrical tube. One or more recessed and/or protruding features 107 may be formed integrally with or otherwise coupled to the housing 105. Such features may extend axially along at least a portion of the housing 105, circumferentially around at least a portion of the housing 105, or a combination thereof, which may assist with securely gripping the apparatus 100. Opposing ends of the housing 105 may be threaded and/or otherwise configured to couple with the first end cap 110 and the interstitial member 115. For example, in the implementation depicted in FIGS. 1 and 2, the housing 105 comprises external threads to couple with the first end cap 110 and internal threads to couple with the interstitial member 115. Of course, other means for coupling the first end cap 110 and/or the interstitial member 115 with the housing 105 are also within the scope of the present disclosure. The housing 105 may comprise metal, plastic, and/or other substantially rigid materials, perhaps including materials that may be disinfected and/or sterilized by conventional and/or future-developed processes, such as for use in a dental office and/or other medical environments.

The housing 105 contains an electrical energy source 108, which in the implementation depicted in FIG. 3 comprises two batteries. The batteries may be alkaline, NiCd, NiMH, NiZn, lithium, lithium ion, silver-oxide, galvanic, electrolytic, wet cells, dry cells, and/or other types of batteries. For example, the batteries may be CR123A batteries, such as those available from ENERGIZER and DURACELL. In other implementations, the electrical energy source 108 may comprise components other than batteries, such as circuitry for connection to a facility electrical system, or a mechanically powered energy source that generates electrical power by shaking, squeezing, winding, and/or otherwise moving the housing 105 and/or another component of the apparatus 100.

The first end cap 110 may comprise a control 112 (FIG. 2) operable to electrically connect the electrical energy source 108 to other electronic components of the apparatus 100 described below. For example, the control 112 may comprise a push button control, a rotatable knob, and/or a switch, although other control types are also within the scope of the present disclosure. The first end cap 110 may also comprise one or more patterned, recessed, and/or protruding portions 113, such as may assist in removing and/or assembling the first end cap 110 to the housing 105.

The interstitial member 115 comprises a light source 117 that may be selectively energized by the electrical energy source 108 via operation of the control 112. The light source 117 may comprise one or more light emitting diodes (LEDs). For example, the light source 117 may be an LED that emits in the blue and/or violet sections of the visible spectrum, such as at a wavelength of about 450 nm or otherwise in the range of about 350 nm to about 500 nm. Intensity of the light energy emitted by the light source 117 may be about 500 mW or otherwise in the range of about 75 mW to about 2000 mW. However, other means may also or alternatively be utilized for the light source 117 within the scope of the present disclosure.

The interstitial member 115 may also comprise one or more components forming an electrical path between the electrical energy source 108 and the light source 117. For example, such an electrical path may comprise a spring and/or other member 118 extending from the interstitial member 115 to the electrical energy source 108, and/or various electronic components and/or circuitry, perhaps including one or more LED drivers, resistors, capacitors, transformers, voltage cut-off coils, low-pass filters, high-pass filters, band-stop filters, band-pass filters, integrated circuits, and/or others (not shown).

The second end cap 120 comprises an optical filtering component 122 that is in substantial optical alignment with the light source 117 and/or light emitted therefrom. The optical filtering component 122 may be or comprise a low-pass filter, a high-pass filter, a band-stop filter, and/or a band-pass filter, although other filters are also within the scope of the present disclosure. An O-ring 124 may be positioned between the optical filtering component 122 and an inside lip 126 of the second end cap 120, such as to create a seal prevent fluid from entering the apparatus via the interface between the optical filtering component 122 and the inside lip 126. The second end cap 120 may further comprise a diffuser 128 positioned to diffuse the light emitted by the light source 117 before the light is incident upon the optical filter component 122, such as to reduce the sharpness of the edges of the beam of light emitted by the light source 117. The optical filtering component 122 and/or the diffuser 128 may comprise glass, plastic, and/or other materials providing the appropriate optical characteristics.

A reflector 130 may also be positioned at least partially within the second end cap 120 in substantial optical alignment between the light source 117 and the optical filtering component 122. An internal surface 132 of the reflector 130 may be polished, painted, and/or otherwise configured to centrally focus the light energy emitted by the light source 117. The reflector 130 may comprise metal, plastic, and/or any other suitable material, and may be secured within the second end cap 120 by a retaining ring 134. For example, the retaining ring 134 may have an internal sloped surface 136 configured to cooperate with an external sloped surface 138 of the reflector 130, such that threading and/or otherwise assembling the retaining ring 134 into corresponding internal threads and/or other features of the second end cap 120 urges the sloped surfaces 136 and 138 together, thus urging the reflector 130 towards the internal lip 126 of the second end cap 120 and compressing the O-ring 124 to form the desired seal. The cooperating sloped surfaces 136 and 138 may also center the reflector 130 relative to a longitudinal axis of the second end cap 120 and/or otherwise aid in optically aligning the reflector 130 between the light source 117 and the optical filtering component 122.

At least a portion of an exterior of at least one of the housing 105, the first end cap 110, the interstitial member 115, and the second end cap 120 may have a cross-sectional shape that is not substantially circular. For example, as shown in the implementation depicted in FIGS. 1-3, a portion of the external surface of the interstitial member 115 may comprise one or more flats 119, such as may aid in preventing the apparatus 100 from rolling when resting on a substantially horizontal surface. However, one or more of the housing 105, the first end cap 110, and the second end cap 120 may alternatively or additionally comprise one or more such features. In addition to the flats 119 shown in FIGS. 1-3, or as an alternative thereto, the cross-sectional shape of the housing 105, the first end cap 110, the interstitial member 115, and/or the second end cap 120 may have at least a portion that is square, rectangular, elliptical, and/or otherwise substantially non-circular. Such features may be integrally formed with one or more corresponding components of the apparatus 100, and/or may be discrete members that are coupled to one or more of such components.

At least a portion of an exterior surface of one or more of the housing 105, the first end cap 110, the interstitial member 115, and the second end cap 120 may also comprise a material that provides substantial gripping force, such as rubber and/or other pliable materials. Such gripping features may be the same as the anti-roll features described above.

As described above, the interface between the optical filtering component 122 and the internal lip 126 of the second end cap 120 may be sealed and/or otherwise made waterproof by compression of the interposing O-ring 124. The interconnection of the other components of the apparatus 100 may also comprise similar sealing and/or other features. For example, the interface between the second end cap 120 and the interstitial member 115 may be sealed and/or otherwise made waterproof by compression of a similar O-ring 140 and/or other means. Similarly, the interface between the interstitial member 115 and the housing 105 may be sealed and/or otherwise made waterproof by compression of a similar O-ring 142 and/or other means. The interface between the housing 105 and the first end cap 110 may also be sealed and/or otherwise made waterproof by compression of a similar O-ring 144 and/or other means. The O-rings 124, 140, 142, and 144 and/or additional or alternative sealing means may seal and/or otherwise make the apparatus 100 waterproof such that, once the apparatus 100 is assembled, no fluids may enter any internal cavity of the apparatus 100.

Having described various details and alternatives with respect to the apparatus 100 shown in FIGS. 1-3, operation of the apparatus 100 will now be described with reference to FIG. 4, which is a schematic view of a dentist, hygienist, and/or other medical personnel 410 utilizing the apparatus 100 to perform oral examination of a patient 420, such as to identify oral cancer, pre-cancer, and/or other oral mucosal abnormalities. The apparatus 100 may be made commercially available as part of a kit that also contains one or more eyewear devices 430 to be worn by the medical personnel 410 and, perhaps, the patient 420 during the oral examination procedure.

The eyewear devices 430 may comprise an optical filtering component to be utilized in conjunction with the optical filtering component 122 shown in FIGS. 1-3. For example, the lenses of the eyewear device(s) 430 may comprise a low-pass filter, and the optical filtering component 122 of the apparatus 100 may comprise a high-pass filter. Alternatively, the lenses of the eyewear device(s) 430 may comprise a high-pass filter, and the optical filtering component of the apparatus 100 may comprise a low-pass filter. Similarly, the lenses of the eyewear device(s) 430 and the optical filtering component of the apparatus 100 may comprise different ones of a low-pass filter, a high-pass filter, a band-stop filter, a band-pass filter, and/or other types of filters. The combination of filters may be operable in conjunction with the light emitted by the apparatus 100 to detect cancerous and/or pre-cancerous regions and/or other mucosal abnormalities of the oral cavity of the patient 420. For example, the two filters may remove all (or substantially all) light emitted by the apparatus 100, including that which may reflect off of surfaces of the oral cavity of the patient 420, such that only the light resulting from fluorescence of the mucosal abnormalities remains visible to the medical personnel 410 wearing the eyewear device 430. Alternatively, the two filters and the light emitted by the apparatus 100 may work in conjunction to dim any light other than the fluorescence emanating from the mucosal abnormalities. The patient 420 may also wear an eyewear device 430 to, for example, block at least a portion of the light emitted by the apparatus 100 from entering their eyes.

FIG. 5 is a schematic view of a kit 500 according to one or more aspects of the present disclosure. The kit 500 may comprise one or more instances of the apparatus 100 shown in FIGS. 1-4 and one or more of the eyewear devices 430 shown in FIG. 4. In the example implementation depicted in FIG. 5, the kit 500 also comprises spare batteries and/or other components 505 of the electrical energy source 108 shown in FIG. 2. The kit 500 may also or instead comprise other components described below and/or shown in subsequent figures, perhaps including apparatus shown in one or more of FIGS. 7-10.

The components of the kit 500 may be packaged in one or more boxes and/or other containers 510, perhaps within an insert 520 having recessed features 530-532 sized to receive corresponding components of the kit 500, such as may aid in protecting the components of the kit from mechanical shocks and/or other forces that may be experienced during handling, shipping, and/or otherwise. For example, the insert 520 may comprise foam and/or other shock-absorbing materials, and may have a first feature 530 sized to receive the apparatus 100 in a manner substantially preventing movement of the apparatus 100 within the container 510. Similarly, a second feature 531 may be sized to receive a predetermined number of batteries (four being shown in FIG. 5), and third features 532 may each be sized to receive one of the eyewear devices 430. Each of the second and third features 531 and 532 may also substantially prevent movement of the batteries and eyewear devices within the container 510. The kit 500 may also comprise an additional insert 540 covering the components of the kit 500 before a cover 550 is assembled to the container 510.

FIG. 6 is a flow-chart diagram of at least a portion of a method 600 according to one or more aspects of the present disclosure. The method 600 may utilize at least a portion of the apparatus described above, such as the apparatus 100 shown in FIGS. 1-5 and/or the eyewear devices 430 shown in FIGS. 4 and 5. The method 600 may also utilize other components described below and/or shown in subsequent figures, perhaps including apparatus shown in one or more of FIGS. 7-10.

The method 600 may comprise cleaning (605) one or more pieces of equipment to be utilized during the method 600. For example, this may entail cleaning the apparatus 100 shown in FIGS. 1-5 and/or the eyewear devices 430 shown in FIGS. 4 and 5. Such cleaning may comprise disinfecting and/or sterilizing the equipment. For example, the apparatus 100 shown in FIGS. 1-5 and/or the eyewear devices 430 shown in FIGS. 4 and 5 may be submersed in a sanitizing solution, such as CAVICIDE (available from UNIMED), MAXICIDE (available from HENRY SCHEIN, INC.), and/or isopropyl alcohol, although other disinfecting and/or sanitizing products may also or alternatively be utilized. Disinfecting and/or sterilizing the equipment may also or alternatively comprise autoclaving and/or thoroughly wiping the equipment with a sanitizing fabric, paper, and/or other wipe.

The method 600 may also comprise donning (610) an eyewear device, such as the eyewear device 430 shown in FIGS. 4 and 5. This may entail one or both of the medical personnel and the patient donning the eyewear.

The light-emitting apparatus 100 shown in FIGS. 1-5 may then be activated (615). As described above, such activation may be via operation of a control of the apparatus, such as a push-button, rotating knob, switch, and/or other control. After activating the apparatus, the medical personnel may then direct (620) light emitted by the activated apparatus into the oral cavity of the patient. For example, the medical personnel may position the light emitting apparatus proximate the patient's oral cavity and orient the apparatus such that all or a substantial portion of the emitted light enters the patient's oral cavity. However, this procedure does not include inserting the light-emitting apparatus into the patient's oral cavity. Thereafter, the medical personnel may visually inspect (625) for fluorescence emitted by cancerous areas, pre-cancerous areas, and/or other mucosal abnormalities of the patient's oral cavity by looking through the eyewear.

The order of the above-described portions of the method 600 may vary within the scope of the present disclosure. For example, the equipment cleaning may be performed prior to activating the light-emitting apparatus and/or after directing the emitted light into the patient's oral cavity. It is also noteworthy that the method 600 does not include utilizing any type of disposable that is discarded after each iteration of the method. For example, the method 600 does not include assembling a rigid or flexible plastic sleeve over the light-emitting apparatus, and thus does not include disposing of such sleeves.

Returning to the example implementation of the screening system 400 shown in FIG. 4, the medical personnel 410 may utilize a camera 450 of a mobile communications device 440 to take images of the oral cavity of the patient 420. An optical component 460 may be operable to spectrally filter images taken by the camera 450 of the mobile communications device 440. The optical component 460 may be or comprise a high-pass, a low-pass filter, a band-stop filter, and/or a band-pass filter, although other types of light filters are also within the scope of the present disclosure. The optical component 460 may remove all (or substantially all) light emitted by the illumination source 100, including that which may reflect off of surfaces of the oral cavity of the patient 420, such that only a fluorescent signal from the tissue may remain visible to the camera 440. Thus, the optical component 460 may be at least functionally similar to the eyewear 430 donned by the medical personnel 410.

The optical component 460 may be made commercially available as part of a kit that also contains the illumination source 100, such as the kit 500 shown in FIG. 5. The kit may also comprise one or more eyewear devices 430 to be worn by the medical personnel 410 and/or the patient 420 during the oral screening procedure. The eyewear devices 430 may be utilized in conjunction with the illumination source 100.

The system 400 may also comprise a computer 470. The computer 470 may be operable to receive spectrally filtered image data from the mobile communications device 440 and/or other computing devices, such as those shown in subsequent figures and described below. The computer 470 may also be operable to store the image data, and perhaps to transmit the image data, such as to another mobile communications device, computer, and/or other computing device.

The mobile communications device 440 is operable to obtain, store, and transmit image data obtained utilizing the camera 450. For example, the mobile communications device 440 may be operable to transmit the image data to at least one of another mobile communications device, the computer 470, and a database. Such database may be embodied or implemented in the computer 470 or another computing device. The database, or a computing device comprising the database, may be operable to be accessed by the mobile communications device 440, another mobile communications device (such as may be remotely located), the computer 470, another computer (such as may be remotely located), and/or another database (such as may be remotely located). The database or a computing device comprising the database may also or instead be operable to transmit at least a portion of the image data to the mobile communications device 440, another mobile communications device (such as may be remotely located), the computer 470, another computer (such as may be remotely located), and/or another database (such as may be remotely located). Communication between the mobile communications device 440, another mobile communications device (such as may be remotely located), the computer 470, another computer (such as may be remotely located), the database comprising the image data received from the mobile communications device 440, and/or another database (such as may be remotely located) may be via one or more of the Internet, a cellular network, a satellite communications network, a local area network, a wireless network, a Wi-Fi connection, other wireless connections (e.g., BLUETOOTH), an Ethernet connection, a digital subscriber line (“DSL”), a telephone line, coaxial cable, and/or other means.

The image data in the database may be anonymous with respect to identification of any patient corresponding to any portion of the image data. The image data may further comprise pathology information associated with each response.

FIG. 7 is a schematic view of at least a portion of apparatus according to one or more aspects of the present disclosure. FIG. 7 depicts an apparatus 700 comprising the optical component 460 and is operable to hold the optical component 460 in alignment with the camera 450 of the mobile communications device 440. The apparatus 700 may comprise a filter structure 710, a contact structure 715, and an attachment structure 720. The filter structure 710 may comprise an opening 712, and the optical component 460 may be affixed within and/or otherwise held in the opening 712.

At least a portion of one or more of the filter structure 710, the contact structure 715, and the attachment structure 720 is operable to contact the mobile communications device 440. That is, the attachment structure 720 connects the filter structure 710 with the contact structure 715 in a manner operable to attach the apparatus 700 to the mobile communications device 440 and align the optical component 460 with the camera 450. For example, the attachment structure 720 may be or comprise a spring 725 operable to bias the filter structure 710 and the contact structure 715 into engagement with opposing surfaces (e.g., front and back surfaces) of the mobile communications device 460, such as by an elastic clamping and/or other type of force. However, although other arrangements are also within the scope of the present disclosure.

FIG. 8 is a perspective view of the apparatus 700 shown in FIG. 7 demonstrating additional, perhaps optional features that may or may not also be depicted in FIG. 7. For example, at least a portion of the filter structure 710 and/or the contact structure 715 may comprise a gripping material 730 that provides substantial gripping force, such as rubber and/or other pliable materials, which may aid in increasing friction between the apparatus 700 and the mobile communications device 440 and aligning the optical component 460 with the camera 450.

The filter structure 710 and/or the contact structure 715 may also comprise one or more finger grooves, recesses, and/or other features 735 that may aid in gripping. The attachment structure 720 may also comprise a pivot 740 and/or otherwise be operable to allow leverage and/or a pinching force to be applied and temporarily separate ends of the filter structure 710 and the contact structure 715, thus allowing insertion of the mobile communications device 440 and alignment of the optical component 460 with the camera 450.

FIG. 9 is a perspective view of another implementation of the apparatus 700 shown in FIGS. 7 and 8, designated herein by reference number 702. The apparatus 702 comprises a substantially continuous length of tempered metal and/or other elastic material that has been folded back on itself, thus forming the filter structure 710, the contact structure 715, and the attachment structure 720. The filter structure 710 may be a substantially planar length of the substantially continuous length of tempered metal and/or other elastic material, and comprises the optical component 460. The filter structure 710 may also comprise a portion of the gripping material (as described above) on an interior surface (not shown, but facing the contact structure 715) and/or other features that may be operable to aid in gripping the mobile communications device 440. The contact structure 715 may include one or more arcuate portions of the substantially continuous length of tempered metal and/or other elastic material, collectively extending in a general direction that may be substantially parallel to the filter structure 710, whether before or after assembly to the mobile communications device 440. The contact structure 715 may also comprise a portion of the gripping material 730 described above. The attachment structure 720 may be a curved portion of the substantially continuous length of tempered metal and/or other elastic material, such as may be operable to urge the filter structure 710 and the contact structure 715 towards each other, perhaps in a manner similar to the operation and/or effect of the spring 725 and/or pivot 740 described above.

FIG. 10 is a block diagram of at least a portion of a system 800 according to one or more aspects of the present disclosure. FIG. 10 depicts an example implementation of the flow of image data spectrally filtered by the optical component 460 and captured by the camera 450 of the mobile communications device 440. Thus, the system 800 may comprise or otherwise operate in conjunction with the mobile communications device 440.

Referring to FIGS. 4 and 10, collectively, image data may be comprised of one or more images of a human oral cavity of a patient 420 taken using the camera 450 with the optical component 460. The image data may thus be received and/or stored by the mobile communications device 440. The image data may further comprise or be associated with pathology information, such as visual and/or textual information that may be associated with the oral cavity images. The image data may also comprise or be associated with a patient 420 corresponding to the oral cavity images, such as visual and/or textual information associated with the patient 420, such as a photo of the patient's face and text identifying the patient 420. However, the image data may also be managed in a manner intending to preserve the anonymity of the patient 420.

The mobile communications device 440 may be operable to transmit image data to the computer 470, another mobile communications device 815, and/or a database 825. The computer 470 may be operable to receive, store, and transmit image data. The database 825 may be as described above, operable to receive, store, allow access to, and transmit image data. The database 825 may receive image data from the mobile communications device 440, and may otherwise be operable to be accessed by at least one of the mobile communications device 440, the computer 470, and another database 840. The database 825 may also or instead receive image data from the computer 470 after the computer 470 has received image data from the mobile communication device 440. The database 825 may also be operable to transmit image data to at least one of the mobile communications device 440, the computer 470, and the additional database 840.

The database 825 may also be protected using one or more usernames and one or more passwords, such as where each password may grant access to the database 825 for a corresponding username. A user may use such username and password to access the database 825 and may access image data for a patient 420 stored in the database 825. Medical personnel 410 may access image data regarding a specific patient 420 via the database 825.

One or more components of the system 800 may further comprise a mobile communications program operable to allow the mobile communications device 440 to transmit, access, and receive image data utilizing the database 520. Such program may be stored in a memory and/or another non-transitory, computer-readable medium, and may include computer-readable instructions executable for capturing the image data with the mobile communications device 440, storing the image data in a memory of the mobile communications device 440, and transmitting image data from the mobile communications device 440, such as to the computer 470, the database 825, and/or another mobile communications device 815.
